I think A because 560×3=1,680
Answer:
The answer to your question is: Yes, it is a solution
Step-by-step explanation:
Point (-2, 3)
Line: y = 2x + 7
Process, replace the point in the line
3 = 2(-2) + 7
3 = -4 + 7
3 = 3
As we got that 3 equals 3, then the point given is a solution of the equation.
The answer to the question is 1 and 3/4
It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:
V α 1/P
To change it to an equality, we introduce a proportionality constant, k. We do as follows:
V = k/P
So, to determine what is asked, we need to first calculate for the value of k.
V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280
Thus, at P = 87 cmHg
V = 17280 / 87
V = 198.62 m^3
